Hi Everyone, I have a question as to my back pay. I was awarded ssdi 8/1/11 and I will receive my 1st ssdi check 9/28/11. How long does it take to receive my back pay? I keep calling SSA and they state it is being worked on. I have also been told by SSA it usually takes 30-45 days to receive it. I desperately need this lump sum as it is a very large amount. Thank you in advance for your responses, Sunsine555
